Table of Contents

This extensive guide will help you to understand why knowing sports betting odds is such a crucial thing for becoming a smart bettor. This guide will help the new bettors as well as those who want to polish their strategy.

Introduction

Odds in sports betting represent the probability of an event occurring and the potential pay-out if it does. Odds may be listed in three different formats: Decimal odds display your total potential pay-out, including the Initial stake. Fractional odds show the potential profit relative to your stake.

Simply put, the greater the odds against a team, the larger the pay-out will be for anyone who bets on that team and wins. For example, 7 to 2 odds mean that for every $2 you wager, you could win $7 if your bet is successful, while 5 to 1 odds mean you could win $5 for every $1 you bet.

For Example:

So let’s start with a money line that’s a straight bet where you are simply choosing winner of said game. the over/under are the total points in a game that are predicted  to possibly be scored; you choose either more or less. Lastly, there is going to be the spread, which is a little more confusing

If a team has a positive spread, they are the underdogs; taking it gives you better odds of a payout. If a team has a negative spread, they are favoured to win, but taking a negative bet produces a smaller payout. Betting on the spread of a game doesn’t necessarily mean choosing the winner; rather, it means betting on how close or far the margin of the game is going to be.

Now you can make any of these bets by themselves, or you can combine them with other bets usually player outcomes, it multiplies your odds and give you a much better pay-out, but you just hit all the bets, this is called a parlay

Types of Odds

The three main types of betting odds are fractional (British) odds, decimal (European) odds, and moneyline (American) odds. These formats are alternate ways of presenting the same thing and have no difference in terms of payouts.

Fractional (British) odds

Fractional odds are also known as British odds, UK odds, or, in that country, traditional odds. They are typically represented with a “/” but can also be represented with a “-“,

For example:

 A fractional listing of 6/1 (six-to-one) odds would mean that you could win $6 for every $1 you wager as well as get the amount you wagered back. In other words, 6/1 is the ratio of the potential profit to the initial bet

Conversely, fractional odds of 1/5 would mean for every $5 you bet, you would only win $1 plus your original stake back.

How to calculate

Denominator / (Denominator + Numerator). Example: 2 / (2 + 5) = 0.285 (or 28.5 %).

Decimal odds

Decimal odds are expressed as a number followed by a decimal point and then a number.

Decimal odds are favoured by betting exchanges because they are the easiest to work with for trading, as they reflect the reciprocal of the probability of an outcome

For example:

2.5 would be expressed as 2.50 in decimal odds. The number after the decimal point is how much you will win if you bet $100 on that outcome.

How to calculate

 calculate decimal odds, you can use the equation Payout = Initial Wager × Decimal Value.

Moneyline Odds

Moneyline in sports betting works by odds being assigned to both teams or players in a sporting event, reflecting the likelihood of them winning. Using a minus to indicate the favourites.

For example:

f Team A (the favourite) is -150, you’d need to bet $150 to win $100 if they win.

How to calculate

Pays +X” (moneyline odds) means that the bet is fair if the probability is p = 100 / (X + 100). “pays −X” (moneyline odds) means that the bet is fair if the probability is p = X / (X + 100).

Connection between Odds and Probability

Odds and probability are both used to express the likelihood of an event occurring in the context of gambling. Probability is expressed as a percentage chance, while odds can be presented in a few different formats, such as a decimal, fraction, or moneyline.

For example for an event that is 40% probable, one could say that the odds are “2 in 5”, “2 to 3 in favor”, “2 to 3 on”, or “3 to 2 against”.
